' To all whom t may concern.'

Be it known that I, ERNEST H. PEABODY, a

citizen of the United States, resid-ing at New York, in thecounty of NewYork and/State of New York, have invented certain new and usefulImprovements l1n ,'Atomizers or Spraying Devices, of which the following1s a' specification.

My invention relateslto liquid atomizers and more particularly to oneforatomizing fuel oil, whereby the ollgmay be atomized and injected int'othe combustion chamberof a furnace, in the form of spray, by means ofmechanical action induced by pressure.

In the accompanying drawing,V which illustrates one embodiment of myinvention, Figure 1 is a central longitudinal section on the plane ofthe lines 1 1 of Fig. 2;.v

Fig. 2, an end elevation; Fig. 3, an enlarged central section on theplane of the line 3 3 of Fig. 4; Fig. 4, a half end elevation and halftransverse section on the plane of the line el-i of Fig. 3; Fig. 5 aviewlooking toward the inner' l'face of the tip; Fig. 6, a side elevation;of the tip;L and Fig.

7, a transverse section' on the plane of theline 7 7 of Fig. 5. 0 ISimilar reference numerals indicate similar parts inthe several views.

Referring tothe drawings the numeral 1f designates lthe body portion ofthe atomizer,

and 1X the goose neck in which is formed thev inlet port 2 leading tothe enlarged chamber 3 is a strainer 6 of any `suitable -nozzle 7 X.

strainer chamber 3, the latter having a rear opening fl closed by a capW'ithinthe construction, the purpose of which is to remove dirt orforeign matter which may be in the oil before the latter is delivered tothe nozzle. The body 1 is reduced at its front -end and isA threaded toreceive the internally threaded portion of a barrel 7. The bore of thebarrel has a slight iiare at -its outer end and over said end is fitteda The latter is formed with a plurality of longitudinalfpassa'ges 8extending from its inner conicalyface to an annularv channel 9 formed initsouter face. Seated uponthe outer lface ofthe nozzle is .a tip 11having a dischargeorice 12 at the apex of a central conical chamber 13.Upon its inner face the tip 11 is formedl with a plurality Of ducts 14:leading tangentially into the chamber 13 from openings 14', whichOpenings, when the tip is in position,

are located over and communicate with the annular channel 9, thusaffording a continuous passage for the flow of the liquid from` thebarrel 7 to the'discharge orifice. The nozzle 7X may be formed with anydesired number of .passages 8, four of said passages being tangentialducts 14 in the face of the tip.

The forward end of the nozzle is eX teriorly threaded to receive a cap10 having a central Opening 10 adapted to receive the central extendedportion of the tip and to bear against the tip to clamp it Ifirmly inposition upon the face of the nozzle. -The face of the cap is concavedat an angle so as to correspond with the -concavity in the end of thetip as clearly indicated in Fig. 3.

shown, with ai corresponding number of In operation, the liquid to beatomized enters through the gooseneck 1x and after passing through thestrainer iows through the barrel 7 and is delivered from the passages 8to the annular channel 9 in the face of the nozzle, through the openingsl14 tO the tangential ducts 14 to the central conical chamber 13 andthence through the discharge Orifice 12. When passing through thecentral chamber 13 of the tip, the liquid is givena 'rapid whirlingmotion, and is a given time and under given condition,

such as natural or forced draft. I-Ieretofore, it has been the practiceto interpose .between the tip and the face of the nozzle a separatemember formed with ducts which, when the parts are assembled, aretangential to the wall" of the tip chamber, In the use of atomizers,itis frequently necessary when working conditions are changed tosubstitute va tip having a different sized discharge orifice, or themember having the 105 tangential ducts and, dueto faulty assembling ofatomizers having discharge orifice in one piece and the tangential ductsin another piece, the proper ratio 0f the areas of' the oriiice and theducts is not maintained.

` IVhen a tip having `a` relatively small 'discharge orifice isassembled with a separate piece having relatively large 'tangentialducts, the 'fuel may emerge in a stream and not beproperly atomized`Also, When a tip with a relatively large discharge orifice is assembledwith a separate piece having relatively small tangential ducts, theatomiza i f tion of the oil may be excessive and fail to meet therequired Working conditions. 'By making a plurality of unitary members,

each having a detinite area ratio between the discharge oriice and thetangential ducts, I thereby provide means to meet vaf rying workingconditions of fuel and pressure and obviate all faultyr assembling.

' l/Vhile I have described' the duets 14- as` Jtangential to the Wall ofthe tip chamber-18,

I desire to include in said lterm Aany degree of ecoentricity of theducts7 Which v'vill give to the liquid a whirling motion in saidChamber.

What I claim and desire to Asecure byLetl ters Patent of the UnitedStates, is i l. In a spraying device, in combination,

a nozzle having a channel in the face there-- of a'nd passages leadingto said channel, al

tip having therein a chamber` with a dis vcharge orifice andduetstangential to the i I Wall-of said chamber, said `duets communieatingWith said channel, and a cap to clamp the tip-to the face of the nozzle.
